Hello. Thanks for reply.
I think I solved it.

I tested two different glossary plugins on the same page. WP Glossary and Name Directory. I changed the description for one Name in the Name Directory. In WP Glossary the same term was used, but I did not change there. Then it appears that Name Directory used the tool tip from WP Glossary (see picture) It was fixed when I changed the WP Glossary to the same as Name Directory on the relevant term.
